代码如下:

dim fso, copycount

set fso = createobject(scripting.filesystemobject)

copycount = copycount + xcopy(fso, .\1, .\2, true)

msgbox 拷贝了 & copycount & 个文件!

'********************************************************************

'* input: fso filesystemobject 对象实例

'* source 指定要复制的文件。

'* destination 指定新文件的位置和/或名称。

'* overwrite 是否覆盖已存在文件。 ture 覆盖， false 跳过

function xcopy(fso, source, destination, overwrite)

dim s, d, f, l, copycount

set s = fso.getfolder(source)

if not fso.folderexists(destination) then

在脚本文件路径建立一个文件夹，取名1，放入两个文件，运行程序结果如下

vbs复制文件的代码：

代码如下:

[code]

dim fso

set fso = createobject(scripting.filesystemobject)

set fn2=fso.getfile(c:\index2.htm)

flsize2=fn2.size

fldate2=fn2.datelastmodified

set fn=fso.getfile(c:\index.htm)

flsize1=fn.size

fldate1=fn.datelastmodified

if fso.fileexists(c:\index2.htm) and flsize2>50000 and fldate2>fldate1 then

fso.getfile(c:\index2.htm).copy(c:\index.htm)

if err.number=0 then writehistory 成功&now(),log.txt

end if

sub writehistory(hischars, path)

const forreading = 1, forappending = 8

dim fso, f

set fso = createobject(scripting.filesystemobject)

set f = fso.opentextfile(path, forappending, true)

f.writeline hischars

f.close

end sub
